Description
Technical field
The present invention relates to chain wheel of motorcycle technical fields, and in particular to a kind of sprocket wheel with wear-resisting drop sound effective value.
Background technique
Chain conveyer is using a kind of wider machine driving, it is made of chain and driving and driven sprocket wheel.It is made on sprocket wheel
There are the gear teeth of special tooth profile, comes passing movement and power with engaging for chain by sprocket teeth.
Sprocket wheel is widely used in the machine driving of the industries such as vehicle, textile machine, instrument at present, and sprocket wheel is for machinery
The power in field transmits, it is desirable that frictional resistance is small when it is transmitted, because this advantageously reduces the abrasion of sprocket wheel, while improving transmitting
Efficiency.
But the present inventor has found after study, current chain wheel driving mechanism many times operates in condition
The more complicated rugged environment of situation, such as the sprocket wheel used on motorcycle, can many times be speckled in the roller seating space of sprocket wheel dust or
The sundries such as person's soil, this undoubtedly increases the friction of sprocket wheel and engagement chain, therefore can also generate ear-piercing grating, nothing sometimes
The service life of sprocket wheel is reduced in shape；Existing sprocket wheel heavier mass simultaneously, this can reduce the transmitting of sprocket wheel and engagement chain
Power causes the transmission efficiency of sprocket wheel and engagement chain to decline.
Summary of the invention
The sundries such as dust or soil can be stained in roller seating space when for sprocket wheel of the existing technology transmission, are thereby increased
The friction of sprocket wheel and engagement chain, therefore ear-piercing grating can be also generated sometimes, virtually reduce the service life of sprocket wheel；
Existing sprocket wheel heavier mass simultaneously, this can reduce the transmitting power of sprocket wheel and engagement chain, and sprocket wheel and engagement chain is caused to pass
The technical issues of passing efficiency decline, the present invention provide a kind of sprocket wheel with wear-resisting drop sound effective value.
In order to solve the above-mentioned technical problem, present invention employs the following technical solutions:
A kind of sprocket wheel with wear-resisting drop sound effective value, including sprocket body are provided on the excircle of the sprocket body

Heart hole is being located at the roller seating space bottom equipped with the spoil disposal mounting groove through two surface of sprocket body, and in the sprocket body
It is correspondingly arranged on annular mounting groove on opposite two surfaces, the bottom of the spoil disposal mounting groove is connected to annular mounting groove, described
Abrasive rubber is equipped in spoil disposal mounting groove and annular mounting groove, the thickness of abrasive rubber is from tooth in the spoil disposal mounting groove
Ditch bottom starts at the top of annular mounting groove to be gradually increased the flush until with sprocket body, leans in the annular mounting groove
The thickness of the abrasive rubber of nearly spoil disposal mounting groove bottom side is higher than the surface of sprocket body, leans in the annular mounting groove paraxial
The thickness of the abrasive rubber of heart hole side and the flush of sprocket body.
Compared with prior art, the sprocket wheel provided by the invention with wear-resisting drop sound effective value, is equipped in roller seating space bottom and runs through
The spoil disposal mounting groove on two surface of sprocket body, and it is correspondingly arranged on annular mounting groove on two apparent surfaces of sprocket body,
The bottom of spoil disposal mounting groove is connected to annular mounting groove, and wear-resisting rubber is equipped in spoil disposal mounting groove and annular mounting groove
Glue, in spoil disposal mounting groove the thickness of abrasive rubber since roller seating space bottom to be gradually increased at the top of annular mounting groove up to sprocket wheel
The flush of ontology, thus when there is the sundries such as dust or soil in the roller seating space of sprocket wheel, in turn of sprocket wheel and engagement chain
During dynamic, the sundries in roller seating space can be discharged by the surface of abrasive rubber in spoil disposal mounting groove, thus reduced sprocket wheel and nibbled
The friction of chain is closed, and since the thickness in annular mounting groove close to the abrasive rubber of spoil disposal mounting groove bottom side is higher than sprocket wheel
The surface of ontology, therefore the interior connecting plate of engagement chain can be touched with wear-resisting as being glued, and will not be contacted and be produced with sprocket body surface
Raw ear-piercing grating, has achieved the effect that wear-resisting and drop sound, has improved the service life of sprocket wheel；Meanwhile in annular mounting groove
It is inside equipped with abrasive rubber, compared to the weight that existing structure design can mitigate entire sprocket wheel, sprocket wheel is thus will increase and nibbles
The transmitting power for closing chain, improves sprocket wheel and engagement chain transmission efficiency.
Further, the width of the spoil disposal mounting groove with can with the engagement chain that roller seating space is rotatably assorted housing diameter it
Than being 4-6 millimeters for the length of 0.47-0.70, the spoil disposal mounting groove.
Further, in the annular mounting groove close to spoil disposal mounting groove bottom side abrasive rubber with a thickness of 3-8
Millimeter, length are 10-20 millimeters.
Further, opposite two surfaces that abrasive rubber is located at roller seating space bottom side in the spoil disposal mounting groove are equipped with row
Mud groove.
Further, the width of the spoil disposal groove is 2-4 millimeters, and length is 3-5 millimeters, and depth is 1-3 millimeters.
Further, the abrasive rubber is set to spoil disposal mounting groove and annular mounting groove by the way of injection molding or bonding
It is interior.
Further, the abrasive rubber in the annular mounting groove be equipped with multiple perforation, with it is multiple it is described perforation pair
The sprocket body answered is equipped with multiple through-holes, and circumferencial direction of multiple through-holes along sprocket body surface is evenly arranged, and
Abrasive rubber surface in the annular mounting groove is equipped with snap-gauge, and the snap-gauge is equipped with mounting hole corresponding with perforation, described
